I didn't say your 'type' of game keeps them from being big sellers, I said your design and implementation decisions do. For example, this patching thing everyone is bitching about. I have no problem about it, but many people do. Just look at this thread to see that. Just for another example, the biggest complaints in reviews about your games are the interfaces, followed by learning curves. People can get past learning curves, but interfaces are to stay. This is just a few examples of what I am referring to as your design and implementation choices. They are fine, and I not talking bad about them. Your choices, no big deal. Only it is fact these choices do not appeal to a large crowd, and when potential people try to tell you what needs to be improved, either nicely or vocally, you tend to just tell them shut up instead of listening to them, and trying to improve your system, which would bring in more players.
